Abstract. Both ice sheets on Greenland and Antarctica are discharging ice into the ocean. In many regions along the coast of the ice sheets, the icebergs calf into a bay. If the addition of icebergs through calving is faster than their transport out of the embayment, the icebergs will be frozen into a mélange with surrounding sea ice in winter. In this case, the buttressing effect of the ice mélange can be considerably stronger than any buttressing by mere sea ice would be. This in turn stabilizes the glacier terminus and leads to a reduction in calving rates. Here we propose a simple but robust buttressing model of ice mélange which can be used in numerical and analytical modeling.

Short summary
Ice loss from Greenland and Antarctica is often cloaked by a melange of ice bergs and sea ice. Here we provide a simple method to parameterize the resulting back stress on the ice flow for large scale projection models.
